amdgpu_irq_add_id(9)

💅 amdgpu_irq_add_id(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the kernel, you've got an amdgpu device, and you need to tell it about an interrupt source. that's literally this function. welcome 🫶

✨ NAME ✨

amdgpu_irq_add_id — register IRQ source 👑

---

🎀 SYNOPSIS 🎀

int amdgpu_irq_add_id (struct amdgpu_device *adev , unsigned int
client_id , unsigned int src_id , struct amdgpu_irq_src *source );

like yes, that's the whole signature, no cap. four args, one int coming back at you 💖

---

🌸 ARGUMENTS 🌸

• adev — the amdgpu device pointer. your main character, fr 🦋
• client_id — the client id. that's it, that's the description 💀
• src_id — the source id. also exactly what it sounds like ✨
• source — the IRQ source pointer. the actual thing you're registering 🌈

---

💅 DESCRIPTION 💅

so what does it do? it registers an IRQ source on a client. that's the whole vibe. iconic, lowkey minimal, but that's the job 👑

---

⭐ RETURN ⭐

0 on success, or an error code otherwise. like, if it's not 0, something went sideways bestie 😭
